Method for preparing superconducting joints
A method for producing a superconducting joint between ends of continuous superconductors, each of said ends comprising a parent metal core and a superconductive alloy layer thereon, said superconductive alloy layer is described comprising a combination of said parent metal and at least one reactive metal; said method comprising the steps of: (A) removing any non-superconductive material from said ends; (B) placing said ends in contact and physically joining them with an electrically conductive joint; (C) depositing a connecting superconductive alloy layer on said ends by a chemical vapor deposition reaction of hydrogen with halides of said parent and reactive metals at a temperature in the range of about 700-950 C; (D) cooling said joined ends; (E) depositing on said joined ends a solder-accepting pure metal; and (F) covering said joined ends with a substantially chemically inert but electrically conductive cladding layer; step C being conducted in an anhydrous inert atmosphere free from elemental oxygen, and step D in an anhydrous inert atmosphere free from elemental hydrogen and elemental oxygen.
